Why am I no longer able to download to You Tube?

I have a You Tube account and have enjoyed downloading iMovie Projects pretty regularly. I haven't changed anything, but now I download a project and it appears to download ....but never shows up on You Tube.. I select share from iMovie and select You Tube and it processes and then the last thing I see is "waiting for verification" real quick and it appears to be done.

Usually, shortly after, I see my video rendering in my You Tube manager.

Now I see nothing after a couple days...

Has anyone else had this problem? Any ideas on fixing it?

Thank you!
